The expression "in brief" is usually used when you want to summarize something quickly or give a brief overview of a topic. It's a way of saying that you're going to explain something briefly, without going into too much detail. You might use it when you're giving a presentation or writing an article to let your audience know that you're going to cover a lot of information, but you're not going to spend a lot of time on each point.
